Lag Time

One positive element to the oil price crash is that consumers are paying less at the pump for their gasoline. Of course it is natural that prices at the pump don’t fall as fast as they do in spot or futures markets – there is a lag – usually measured in days. However, while average retail gas prices have fallen over $1/Gal in the past year – more or less in line with spot and futures markets, it seems that changes to diesel prices at the pump have lagged further behind refinery prices. The result is that retail buyers filling their diesel truck at the pump have benefited far less from the oil price windfall than gasoline powered vehicle owners – at least so far. Today we review the data.
